Hi, not sure if this is the place for this but after failing to find it for ages im sick of it . Its nothing amazing but its been in my head for ages.

sorry for the vauge description.
starts up by a guy and a girl together, after a few pages the guy runs of to the bathroom to masturbate.

while this happens it cuts to another girl who is running home and needs to use the bathroom. ends up jumping into the bathroom in on the guy masterbating and accidentally fucks him(silly i know). they proceed to fuck in the bathroom while the first girl knocka on the door and tries to get in but the door is blocked by them fucking.

thats all i rememver about it. i dont even remember what the characters look like. i know its not very helpful but ive been trying to find this for so long that anythjng would be great. ive tried searching for every posible tag combination and i give up

thanks for any help you can give
